Hello,

Is there an easy function for switching list to matrix. My list is of
genetic distances between species pairs:

A A 0
A B .5
A C .25
B C .5

and I want a distance matrix such as:

   A  B  C
A 0  .5 .25
B .5  0 .5
C .25 .5 0

for use in a mantel test.

Thank you for the help!

cheers,
charlie
